FAQs on Short Tricks: Motion Under the Gravity Questions Video Lecture - Physics Class 11 - NEET

1. What is motion under gravity?
Ans. Motion under gravity refers to the movement of an object when influenced solely by the force of gravity. It is commonly observed when objects are thrown upwards or dropped from a certain height.
2. How does gravity affect motion?
Ans. Gravity accelerates objects towards the Earth at a constant rate of approximately 9.8 meters per second squared. This acceleration affects the motion of objects by constantly pulling them downwards, causing them to accelerate or decelerate depending on the direction of the force.
3. What is the formula to calculate the time of flight for an object under gravity?
Ans. The formula to calculate the time of flight for an object under gravity is given by t = 2v₀/g, where t is the time of flight, v₀ is the initial velocity, and g is the acceleration due to gravity.
4. How can we calculate the maximum height attained by an object under gravity?
Ans. The maximum height attained by an object under gravity can be calculated using the formula h = v₀²/2g, where h is the maximum height, v₀ is the initial velocity, and g is the acceleration due to gravity.
5. What is the relationship between the range and the angle of projection in motion under gravity?
Ans. The range of a projectile in motion under gravity is directly proportional to the sine of twice the angle of projection. This means that as the angle of projection increases, the range also increases, reaching its maximum value at 45 degrees.
